Resilient sheet of connect port for isolating electromagnetic waves

Abstract

The present invention proposes a resilient sheet of connect port for isolating EM waves, which sheet comprises a main body of rectangular sheet and an outer frame bent toward the same direction from the edge of the main body. The cross section of the outer frame is U-shaped, and a plurality of bumps equally spaced are formed on the outer side surface thereof. A plurality of resilient plates and resilient projective ears slanting forwards are formed on the edge of the outer frame. A raised point is formed on each of the resilient projective ears. The raised points will contact a rear plate set of the case of a computer. The resilient projective ears will be bent backwards due to the push of the rear plate set.

I claim:  
     
       1. A resilient sheet of connect port for isolating electromagnetic waves, comprising: 
       a main body of rectangular sheet;  
       an outer frame bent toward the same direction from four edges of said main body, the cross section of said outer frame being U-shaped, a plurality of bumps equally spaced being formed on the outer side surface of said outer frame, said resilient sheet of connect port being retained on a rear window of the case of a computer through said bumps; and  
       a plurality of resilient plates and resilient projective ears formed at the longitudinal and transverse positions along the outer edge of said outer frame, each said resilient projective ear being situated between two adjacent said resilient plates, a raised point being formed on each said resilient projective ear, said raised points contacting on said rear plate set of the case of the computer to increase the count of contact points of said resilient plates with said rear plate set so that the object of isolating electromagnetic waves can be achieved.  
     
     
       2. The resilient sheet of a connect port for isolating electromagnetic waves as claimed in  claim 1 , wherein a gap is formed between said resilient plate and said resilient projective ear. 
     
     
       3. The resilient sheet of a connect port for isolating electromagnetic waves as claimed in  claim 1 , wherein an indication faceplate is joined on said main body, and insertion holes of connector corresponding to insertion holes at the rear window of the case of the computer are formed on said indication faceplate and said main body.
